Pedigree Pre-Assessment

Aa, DD, bB, yy are all examples of

• genotypes
• phenotypes

Which of the following genotypes is homozygous dominant?

• A

• Aa

• AA

• aa

In a flowering plant species, red flower color (R) is dominant over white flower color (r). What is the genotype of any red-flowering plant resulting from this species?

• rr
• R
• RR
• RR or Rr

In Mendelian genetics (simple dominance) what type of phenotype is expressed when the genotype is AA or Aa?

• dominant

• recessive

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross two speckled flowers.

• 1 red, 2 speckled, 1 blue

• 2 red, 2 blue

• 2 blue, 2 speckled

• 1 red, 1 speckled, 2 blue

When one allele is not dominant over the other, resulting in both traits expressed in a heterozygous individual.....

• Incomplete Dominance

• Codominance

What gamete possibilities could come from this parent's genotype?

• AB, AB, aB, aB
• Ab, AB, Ab, ab
• Ab, Ab, Ab, Ab
• AB, aB, ab, aB

What goes in box 1

• AABb
• AABB
• aabb
• AaBb

Which of the following are genotypes for blood type B?

• I^A I^A and I^A I^B

• I^B I^B and ii

• I^B I^B and I^B i

• I^A I^B and I^A I^B

The previous questions were about a few of the concepts we learned in the last few classes. Take three minutes to ask questions or identify concepts where you're still struggling. Refer to the list of learning goals below. What do you still need to work on?

--Mendelian Genetics and Punnett Squares

--Incomplete and Co-dominance

--Multiple Alleles (blood type)

--Dihybrid Crosses
